What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background and aim Endodontically treated teeth often require post placement to reinforce structural integrity. Fiber posts are preferred over metallic ones due to their elastic modulus, which is closer to that of dentin. Dimethyl sulfoxide (DMSO), known for its tissue penetration and solvent properties, has recently been explored as a dentin pretreatment to enhance adhesive performance. This study aimed to evaluate the effect of DMSO pretreatment on the push-out bond strength of fiber posts luted with different adhesive protocols, including self-etch and total-etch systems. Materials and methods Forty extracted human teeth were standardized and subjected to root canal treatment. Following post space preparation, the teeth were randomly divided into four groups (n = 10) based on adhesive protocols: Group I, total-etch + DMSO + single-step, seventh-generation universal adhesive (Palfique, Tokuyama Dental Corp., Tokyo, Japan); Group II, total-etch + primer + DMSO + three-step, fourth-generation adhesive (FL Bond II System, Shofu Inc., Kyoto, Japan); Group III, total-etch + DMSO + primer + three-step, fourth-generation adhesive (FL Bond II System, Shofu Inc.); and Group IV, self-etch + DMSO + single-step, seventh-generation universal adhesive (Palfique, Tokuyama Dental Corp.). Fiber posts were cemented using Estecem Plus resin cement and light-cured. All specimens were sectioned and subjected to push-out bond strength testing using a universal testing machine. Data were analyzed using IBM SPSS Statistics for Windows, Version 25.0 (Released 2017; IBM Corp., Armonk, NY, USA). One-way ANOVA was used for intergroup comparisons, Tukey's post hoc test for multiple pairwise comparisons, and repeated-measures ANOVA for intragroup comparisons. Statistical significance was set at p < 0.05. Results Group II (2.34 MPa) showed the highest mean push-out bond strength. Statistically significant differences were observed between Groups II (2.34 MPa) and IV (1.39 MPa), III (2.24 MPa) and IV (1.39 MPa), I (0.68 MPa) and II (2.34 MPa), and I (0.68 MPa) and III (2.24 MPa). No significant differences were found between Groups II (2.34 MPa) and III (2.24 MPa) or between Groups I (0.68 MPa) and IV (1.39 MPa). Conclusions The application of DMSO in combination with the FL Bond II System, either before or after primer application, significantly enhanced the bond strength of fiber posts. Universal adhesives showed lower bond strength regardless of the etching protocol, suggesting that DMSO pretreatment is more effective when used with multistep adhesive systems.
